America would win. Have you learned anything from the 2 world wars? The country that started it will lose!
USA Has neuclear bombs *sorry for the misspelling* which can destroy equestria. Friendship will not make USA lose. It will make equestria lose because most of America's military soldiers joined because they grew up loving the nation.
Wrong. Equestria still would lose with Celestia too. Sure they may think about time but u.s soldiers fight day and night.
